Circulatory System is responsible for delivering oxygen, water and nutrients to various body systems and cells while also transporting waste away (e.g. carbon dioxide). The circulatory system consists of the heart, blood vessels such as aorta, vein, ventricle, capillaries and blood itself.

The heart is essentially a muscle that pumps blood ensuring its movement throughout the body. The heart is located a bit to the left from the center of one’s chest. Well functioning circulatory system depends on a health heart, which in turn is dependent on regular exercises, healthy eating and not smoking.

The blood vessels carry blood throughout the body. The blood flows away from the heart through arteries. Arteries carry blood high in oxygen content. Veins on the other hand carry blood towards the heart. Capillaries are small blood vessels that connect arteries to veins. Nutrients, oxygen, water and carbon dioxide pass through the capillary walls.

The blood is the red substance that transports all the above throughout the body cells. The blood consists of red blood cells, white blood cells, platelets and plasma. Red blood cells carry oxygen from the lungs towards body cells and deliver carbon dioxide back. Carbon dioxide is than exhaled from the lungs. White blood cells help the body fight infections by destroying germs. Platelets are cells that stop bleeding by forming a natural seal to the damaged blood vessel. The red blood cells, white blood cells and platelets are formed by the bone marrow, which is a soft tissue in the bones. Plasma is the liquid part of the blood, produced in the liver, which makes about half of the blood content. All the above make up the circulatory system presented below:

Hyperloop diagram – The hyperloop diagram displays the fundamentals of this new transportation technology. Is Hyper loop the transportation of the future over long distances? This may well be the case given its potential. Elon Musk played a key role in invention of the hyperloop concept.

Hyperloop’s key components are as follows the capsule, compressor, vacuum tube, propulsion, air bearings and the actual payload. Compressor is a giant fan on the front of the capsule and is what makes the hyperloop possible, transferring huge volumes of air away from the nose. Without it, the pod would be pushing all the air in front of it, which would make it a lot more expensive including the need to develop a bigger tube.

Speaking of the vacuum tube, capsule will travel in a near vacuum to reduce drag significantly. Valves and pumps will keep internal air pressure at about 100 Pascals or one-thousandth the air pressure at sea level. Nitrogen could be injected into the tube as well.

Propulsion: the Hyperloop capsule speeds along a magnetic river propelled by linear induction motors spaced along the tube or installed as a continuous strip. Linear induction, used on maglev trains has no moving parts and low maintenance costs.

Air bearings – the capsule will use cushion of air pumped from the bottom of lunch-tray-size sleds. Landing gear may need to be deployed as it comes to a stop.

Hyperloop payload will be a capsule of about 70 feet long, big enough to hold standard 40 foot container. The capsule could accelerate from 0 to 750 mph in less than 60 seconds.

The muscular system diagram depicts the anatomy of various human muscles including biceps, tripezius, deltoid, triceps, abdominis (abs) and other key muscle groups. While multiple groups exists, overall, there are 3 different types of muscle tissues: skeletal, visceral and cardiac.

Skeletal muscles are attached to the bones, often via a joint with muscles used to bring the bones closer together. They are usually attached to the skeleton. These muscles are also controlled consciously by a human while performing such tasks as running, speaking and typing. The cells in these skeletal muscles are made of multiple progenitor cells coming together into the long and strong fibers. The diagram below summarizes skeletal muscles.

Visceral muscles are the weakest of all muscles and are a part of the organs and body systems such as blood vessels and stomach. They are used to move matter through the organ (e.g. blood, food, etc) and appear smooth and uniform when looking at the microscope. They are unconsciously controlled by the brain.

Cardiac muscle is located in the heart and pumps blood through the arteries. Similarly to visceral muscles, it is not controlled consciously; instead it stimulates itself while adjusting to the hormone levels. Cardiac tissue is very strong.

Essay Structure – The below essay structure diagram explains how a typical essay should be structured including introduction, 3 key body paragraphs or arguments and conclusion. The creation of a good essay requires a lot of knowledge from the author but having a good structure helps to make the message even more clear.

Great arguments and knowledge structured poorly may result in audience losing focus and interest while even a fairly weak arguments structured well can result in getting reader’s attention.

The first paragraph, the introduction, starts with a general idea and gradually gets more and more specific. It ends with the thesis, one sentence that tells the reader what is the main point and argument of the essay. The triangle illustrates the general to specific / focused structure, gradually getting narrower and coming to the main point.

The body of the essay proves or elaborates the thesis further. Body usually has three paragraphs. The longer papers just add more body paragraphs but the overall structure works regardless of the length of the paper. Important to note that having too many arguments may result in reader thinking you are trying to ‘oversell’ your point and could result in loss of focus.

On the essay structure diagram below, the yellow portion in the red paragraph shows the location of the transitional phrase and so does the red segment in the orange segment.

It is best to place a good argument first to capture users attention. The weakest argument usually goes in the middle. Your strongest argument should go last so you finish on a strong note and get your reader to agree with you.

In the conclusion, the structure is reversed with the specific thesis coming first and the ever more general sentences coming last. It is important that the last sentence creates a good ending for the paper. Sometime this could be inspirational or a generic truism. Do not introduce new ideas in the conclusion.

Following this structure will help you write excellent essays. This is very important to get your ideas across. Communicating at one’s best ensures people understand each other. Communication is key to the betterment of our world. 🙂 Note how this last paragraph starts off with specific point and concludes in a generic inspirational phrase.

Plot Diagram illustrates the typical development of a book plot. It consists of the exposition, rising action, climax, falling action and resolution. The exposition is the beginning of the story where the setting and the characters are first introduced to the reader. The setting is where the story takes place. Rising action represents the development of the story through the series of conflicts faced by the main characters. This leads to the climax or the peak of the story, where the main events occur. The falling action are the events that lead to the end of the story, i.e. how everything gets settled and main characters ‘recover’ from the main conflict. The resolution is the end of the story.

Most novels and books follow the above plot structure since it is most natural for story telling and human comprehension. At the same time, there are a few books and movies nowadays that try to break through this traditional narrative approach to writing literature. The below plot not only shows the stages of the plot but also the degree / severity of the conflicts.

Microscope diagram below depicts parts of a typical light or optical microscope. Microscope uses lenses and light to optically increase the size of an image of whatever is being magnified. This is achieved through a magnifying glass, which varies in magnification and quality. Other parts of a microscope include eyepiece lens, tube, arm, base, illuminator, stage, rack stop, nosepiece and a diaphragm. Lets discuss each component in more detail.

The Base is the bottom of the microscope. Arms support the tube and are attached to the base. The tube is what integrates the objective lenses to the eyepiece lens. The latter is what a user sees through and is located at the top of the microscope. There are multiple objective lenses in a microscope that come in a variety of magnification powers. The final magnification is a multiple of the eyepiece lens and the objective lens (e.g. 10x eyepiece multiplied by 40x objective gives you 400x magnification). The lens with the lowest magnification are called short and with the highest are referred to as long. The objective lenses are switched with a revolving nosepiece also called a turret. the relevant proximity of these lenses to the slide is adjusted by the rack stop.

Illuminator is the the source of light or a mirror. The mirror microscope uses light from outside to display the image. The light comes from bottom of the stage, which is a platform where slides are inserted between stage clips.

How to Focus a Microscope:
1) Start with the lowest power objective lens.
2) Put the lens down close to the slide.
3) View through the eyepiece and focus upward until the image is sharp.
4) Switch objective lenses for greater magnification while adjusting the focus knob.

Nose diagram – Human nose helps one breathe, smell, and taste. The nose is the part of the respiratory tract that sits front and center on your face. The Human Nose is composed of bone and cartilage on the outside, is one of the most noticeable features of the human face.

Ear Diagram below shows the various parts of a human ear. Ear anatomy includes external, middle and inner parts.
The outside portion, called the outer ear includes pinna, a ridged cartilage, through which sound travels into the short tube called the external auditory canal. This canal goes all the way to the eardrum.

Sound waves vibrate the eardrum connected to the cochlea, part of the inner ear. Sounds are then converted into nerve impulses that are further conducted to the brain. The semicircular canals are attached to the nerves and cochlea in the inner ear and are filled with fluid. Their function is to communicate the position of the head and body’s balance to the brain. The eustachian tube allows fluid to flow from the middle ear into the throat.

Essentially, a human ear is a system consisting of three organs that work together on hearing and balance in conjunction with the nervous system. The diagram below displays the human ear anatomy.

Cancer Types. The below cancer types diagram depicts various cancer-related statistics for USA and globally. The diagram lists most common and most deadly cancer types for men and women. Combination of mortality rate and occurrence frequency results in higher number of deaths.

For men leading cancer types are lung, prostate, colorectal, pancreatic and liver. For women it is lung, breast, stomach, colorectal and ovarian. The below diagram explains the different types and provides relevant cancer stats for men and women.

The basic astrology zodiac elements are air, water, fire, earth. The elements are alternating. There are 12 signs. These signs are often used to predict one’s personality, create horoscopes and help with matching one’s love partners.

Thyroid diagram. The below diagram depicts thyroid gland and larynx. Thyroid is an endocrine gland located in the head and neck. The thyroid gland and parathyroid glands are a group of endocrine glands located in the base of the neck below Adam’s apple. Thyroid consists of two lobes connected by an isthmus.

Thyroid produces thyroid hormones, which influence the metabolic rate and protein synthesis. These hormones also impact numerous areas of development and overall person’s well-being. Thyroid hormones, T3 and T4, are synthesized from iodine and tyrosine. In addition, the thyroid makes calcitonin, a hormone that participates in calcium homeostasis.

Obesity Diagram – Obesity Chart – Obesity charts show the level of obesity for women and men. This type of graphic is often referred to as weight height chart. So what weight is considered obese? What is obesity in general? Am I obese or am I overweight and what is the difference? These questions can be answered by analyzing the below diagram, which provides an objective measurement and serves as good guidance in terms of whether one has excessive weight and fat.

Height is an important component as it is expected that tall individuals will have more weight. Bone density may be another factor and one’s appearance may not fully correspond to the obesity indicator. Obesity weight for a given height is presented in the below table. The below chart displays overweight, obese, normal and underweight weight by person’s height as well as a corresponding Body Mass Index (BMI).
